Description of the Invention: TECHNICAL FIELD Embodiments of the present invention relate to an electroluminescent display (for example, an organic light emitting diode (OLED) display device) and a method of driving the same. More specifically, embodiments of the present invention relate to an OLED display device capable of displaying an image having a uniform shell degree and a method of driving the same. [Prior Art] There have been many attempts to develop various flat-panel displays capable of reducing the weight and volume characteristics typical of cathode ray tubes. For example, a face-to-face display includes a liquid crystal display, a field emission display, a money display panel, a 〇led display device, and the like. An OLED display device generates an image by using a light-emitting diode, and the light-emitting diode system generates light by recombining electrons and holes. The 〇led display device may have advantages such as fast response time and/or relatively low power consumption. The OLED display device can utilize a voltage driving mode in which a voltage is used as a data signal, or a current driving mode in which a known current is used as a data signal. The voltage driving mode can divide a predetermined voltage into a plurality of gray levels' and display a predetermined image by using one of the powers supplied to the bank as a data signal to the pixels. However, in the voltage driving mode 'down', it is likely to be difficult to change the critical electric grind and electron mobility of the individual material driving transistors in each pixel of the display H. ~ Like 6 200828241 The first 1 current drive mode can display an image by supplying a (four) word (four) stream as a material to the pixel of the display. This current drive mode can display uneven images regardless of the threshold voltage of the individual drive transistors. However, because the current drive mode uses microcurrent as the data signal, the current drive mode may not be possible. Charging - the desired voltage to individual pixels in a given time. Therefore, using this current drive mode to drive a large area circuit may not be possible. More specifically, when the micro current is made (four) When data signals, because of the load capacitance in each data line, a large amount of time may be required for charging the pixels. This current drive mode may be disadvantageous because it may be very difficult to design - using micro current to display A large number of grayscales The information disclosed above in the prior art is only for enhancing the understanding of the background of the present invention, and thus it may contain 匕3 and does not constitute a common skill in the technology for the technology.

The driving transistor MD can supply a driving or control current corresponding to a voltage applied to the second node to the 〇LED from the first power source ELVDD via the fifth transistor M5. Light having a predetermined brightness can then be emitted by the OLED. The exemplified embodiments of the present invention have been disclosed herein, and are intended to be illustrative and illustrative and not restrictive. Thus, those skilled in the art will appreciate that various modifications in form and detail can be made without departing from the spirit of the invention as set forth in the following claims. And category.
